BOHLENDER´s
Commitment
For the environment
BOHLENDER takes its responsibility for the envi- ronment seriously. Our responsibility is not only a respectful handling of natural resources but also avoiding waste and integration of recycling in the production process.
» Even during the machining of PTFE (e. g. drilling, turning or milling) all cuttings are collected by means of suction through a special tube system directly on our machines. All chips as well as rem- nants of semi-finished items are sorted according to their purity and stored contamination-free in lar- ge containers before later being recycled. During recycling, all chips and remnants are converted by a specially developed process into usable semi- finished items.
» With regard to the environment, disposable pro- ducts are no longer in our mind. Therefore all our products are designed for long-time use.
» Generation of chips can be avoided by using moulded parts. In addition, moulding reduces the consumption of PTFE powder and energy.
» Products made of the most common fluoroplas- tics are free of plasticizers and solvents. Thus, they are not harmful for the environment.
No PFOA / APFO use in production
Formerly, perfluorooctanoic acid (PFOA) respec- tively sal ammoniac (APFO) have been used as additives in the polymerisation process during the production of polytetrafluorethylene (PTFE).
The use of these additives was obligatory in the emission polymerization process but has also partly been used in the suspension polymerisation process.
Although PFOA respectively APFO are almost com- pletely removed from the final product and can mostly be regained during the production process, the well-known manufacturers of PTFE have com- mitted themselves by self-declaration to waive the use of PFOA and APFO in any production process as of the production year 2015. With the renunci- ation of PFOA and APFO it is ensured that these chemicals, which have not been classified as toxical so far, do not accumulate in the environment.
By supplier agreements, BOHLENDER GmbH en- sures that all fluoroplastic materials used for our products have been manufactured without the use of the additives PFOA and/or APFO. Besides PTFE and PTFE-TFM, this includes also all fluoro-thermo- plastics such as PFA, FEP ETFE or PVDF.
